Equipment in operation

The following rules should be observed in order
to ensure the correct operation of the heat
exchangers:
1. Do not exceed permissible pressure and
temperature.
2. Avoid abrupt changes in temperature and
pressure of the working fluids. Maximum
difference in temperature of the working fluids
cannot exceed 150°C/302°F.
3. Avoid excessive fouling of the heat exchangers.
4. Clean heat exchangers periodically according
to the below-mentioned recommendations:
– heat exchangers operating in the central
heating system every 18 months at least;
– heat exchangers operating in the domestic hot
water system every 12 months at least;
– cleaning frequency should be increased in case
of disadvantageous operation conditions.

Protection against freezing

Risk of freezing of the working media at the low
temperatures should be taken into account. In
order to avoid any damage to the heat exchanger
caused by freezing, the operated medium must
contain the anti-freeze agent under working
conditions.
Heat exchangers that are turned off at the
ambient temperature lower than the freezing
point of the medium should be emptied and dried.
